Installing, Updating, Backup and Restore Guide for OP6/6T - OnePlus 6T Guides, News, & Discussion

This is a bit late but why not. THIS IS A COMPILATION OF ALL THE OS METHODS YOU NEED FOR THE OP6/6T.
ENJOY my guide
DISCLAIMER:
*I am not responsible for bricked devices, damage to your device*
Sorry for a long list of methods, some work for others and some don't. But I recommend to pick a method and stick to it. Maybe read the part at the top as some have notes about mine or someone else's experience/recommendation. Don't skip steps and follow each step.
If stuck, just ask and I or anyone else will try and help
I am here to post methods for anyone who is interested/need help. I have tested these myself and helped others who may be struggling

Fastboot ROM for OP6 + OP6T from mauronofrio
MSMDownload tools for OP6 + OP6T from Some_Random_Username
IMPORTANT NOTES!
YOU REQUIRE Platform Tools (Fastboot Tools) IN ORDER TO USE THE METHODS IN THIS GUIDE AS TWRP NEEDS TO BE INSTALLED!
YOU NEED TO HAVE A UNLOCKED BOOTLOADER AS WELL!
For GAPPS, u can use the same or a updated version of the package. But has to be the same type u used to install it like (stock, full, Omni, basic, etc). ONLY FLASH/INSTALL IF the RESTORE SCRIPT DIDN'T SHOW UP during a DIRTY FLASH/UPDATE AND ONLY FLASH AFTER REBOOTING TO RECOVERY AFTER FLASHING/INSTALLING A OS/BUILD ZIP FILE!
How to get Platform Tools
These tools are used to install TWRP, to unlock the bootloader of your device and is needed to use the METHODS in this guide.
Download the platform tools.zip of your software platform (Mac, Windows, Linux)
Extract the platform-tools.zip
To use it go into your platform-tools folder
Press shift + right-click and choose command prompt or PowerShell
Connect your device when it's in fastboot mode and done
How to install TWRP
Sadly this Guide is for Windows, but other platforms like Mac or Linux can be found online.
YOU CAN USE THIS METHOD TO INSTALL A NEWER VERSION OF TWRP TOO
You need to have downloaded Platform Tools which the link is attached below.
Transfer the TWRP.img file into the platform-tools folder
Now transfer TWRP.zip into your device's internal storage. (connect -> allow file transfer -> drag and drop files)
If you want root download and transfer magisk.apk and the link is supplied below. Also, RENAME from .apk to .zip
Now we must boot into fastboot mode. (Either do it with the advanced reboot in developer options or power off device -> boot recovery Vol - + power -> boot to bootloader or power off device -> press Vol Up + Vol down + power)
Now connect your device to a Windows device
Press shift + right-click. Choose command prompt or PowerShell
Enter "fastboot devices" and your device should be displayed if it's connected
Type "fastboot boot twrp" file name (do twrp + press tab) and press enter
Then you should be booted into TWRP
Enter the password and swipe to allow modifications
Press install and find your TWRP.zip file
Swipe to confirm Flash
If you want root do this
Press the back arrow and find your magisk.zip
Swipe to confirm Flash
Reboot to the system and done
Otherwise, just reboot to system. Up to u
Installing a Custom ROM
Install Custom ROM on OP6T from OOS
Make sure u have BACKED UP your device and have the latest OOS installed in both slots. If u do, go to Method 3.
If u have finalize.zip, go to Method 2.
Method 1
If u don't have OOS installed in both slots or finalize.zip, use this method.
Transfer OOS.zip file, TWRP.zip, Build.zip (Custom ROM zip file) into internal storage.
Boot to Bootloader
Boot TWRP
Flash OOS + TWRP
reboot recovery
Flash OOS + TWRP
Reboot recovery
Flash Build.zip (Custom ROM zip file)
Flash TWRP
If the ROM doesn't have GApps included do this
Reboot to recovery
Flash Gapps if not included
Format data
Reboot to system
Otherwise, just Format data -> reboot to system. Up to u
If you want root do this
Reboot to recovery
Flash Magisk
Reboot to system and done
Otherwise, just reboot to system. Up to u
Method 2
If u have finalize.zip, do this method. Using finalize is way quicker as there's less flashing and rebooting.
Transfer OOS.zip file, finalize.zip, TWRP.zip, Build.zip (Custom ROM zip file) into internal storage.
Boot to Bootloader
Boot to TWRP
Flash OOS + finalize
Boot to Bootloader

If you want root do this
Reboot to recovery
Flash Magisk
Reboot to system and done
Otherwise, just reboot to system. Up to u
Installing Custom Rom not from OOS
You can use finalize method or just flash OOS + TWRP way. The finalize way is there for some who like less flashing and rebooting.
Using the methods in Install Custom ROM on OP6T from OOS
Using the old way, use Method 1
Using finalize.zip, use Method 2
Remember to factory reset (wipe, but no need to wipe internal storage)
Backing Up OOS and Custom ROM
Make sure u have installed the latest TWRP version from mauronofrio
You should use TitaniumBackup or Migrate to back up your apps and contacts.
Also, have a copy of your Internal Storage folders if u have important files.
TWRP Backup backs up your OS like Apps, settings and set up, but not internal storage.
NEVER BACKUP SYSTEM AND VENDOR! ONLY SYSTEM.IMG or VENDOR.IMG IF YOU HAVE TO!
Restoring it makes going back way easier like you have never left
Or you can go manually and try and restore everything, but why do that when you got TWRP?
I do both ways of backing up
Backing up OOS
Boot TWRP recovery
Choose Backup
Choose boot, data. YOU DO NOT NEED TO BACKUP System.img and Vendor.img!
Swipe to backup
Once done, either boot to system or mount
Transfer the whole TWRP folder onto a storage device
Done
Backing up a Custom ROM
Boot TWRP recovery
Choose Backup
Choose boot, data, system.img, vendor.img
Swipe to backup
Once done, either boot to system or mount
Transfer the whole TWRP folder onto a storage device
Done
Restoring OOS and Custom ROM
Restoring OOS TWRP Backup
To restore OOS use either fastboot ROM or MSM. Fastboot is the fastest and easiest way if u have a TWRP backup which there's a method to how to make one in this guide. BUT if you are restoring to go back to stock OOS then use MSM
I use Fastboot ROM restore for that too as we are restoring our data anyways and also for switching/installing a custom ROM. Much easier in my experience.
DOWNLOAD FULL ZIP OF OOS version of your TWRP backup otherwise you could risk doing the whole restore method again OR setup from SCRATCH! IF you aren't restoring a TWRP backup, I recommend either TRANSFER or DOWNLOAD via WiFi or oxygen updater, a UPDATED version of OOS AFTER doing either fastboot ROM or MSM restore methods. As they restore a old version of OOS!
Restoring using Fastboot ROM
Download fastboot ROM of your choice using the link in the Download Link section.
Extract/ un-zip
Boot your device into fastboot mode (Either do it with the advanced reboot in developer options or power off device -> boot recovery Vol - + power -> boot to bootloader or power off device -> press Vol Up + Vol down + power)
Click flash-all.bat
Restoring using MSM Download Tool
Download latest MSM version of your choice using the link in the Download Link section.
Extract/ un-zip
Click on MSM tool .exe file
Turn off device
HOLD BOTH volume buttons
Connect your phone
Wait for your device to be connected and it should show as green
Click verify to check and press start
Wait till phone reboots
The setup device and u can carrying on restoring your device if u don't want a unlock bootloader or return to what your device was like before.
Go into developer options
Allow OEM unlocking
Reboot to bootloader
Enter "fastboot devices" to check your device is connected
Enter "fastboot oem unlock"
Swipe for yes
Then it will reboot again
continue to the next method
For both fastboot and MSM
Once booted into system, set it up and update to OOS version of your TWRP backup.
Download the full zip using the link in the Download Link section.
Transfer the OOS .zip to internal storage.
Go into settings -> system update -> Update via local upgrade -> find zip file and press install
Do this twice to make sure you have installed that version of OOS in both slots
Boot to bootloader
Boot TWRP
Install TWRP
Reboot recovery
Transfer whole TWRP Folder into internal storage
Restore only boot and data
Swipe to restore
If you have backed up your internal storage folders do this
Reboot to recovery
Transfer all your internal storage folders
Reboot to system and done
Otherwise, just reboot to system. U can update OOS as well if it's outdated. The method is below to update OOS with ROOT. Up to u
RESTORING TWRP BACKUP HAS ISSUES ON THESE ROMs
CrDroid (Method 1 + 2 don't work). Method 3 works (install Gapps if the ROM doesn't have it!)
Restoring a Custom ROM TWRP backup 1
I tried using this method, but it didn't work for me.
You can use this method to switch ROMs too

Boot to bootloader, boot TWRP
Flash TWRP
Reboot Recovery
Transfer twrp backup
Restore System.img, Vendor.img and boot
Boot to system and setup system

I had an issue with this method where rebooting system it was from fresh and my data didn't restore. If this happened to you, then do method 2 (Restoring a Custom ROM TWRP Backup 2)
Restoring a Custom ROM TWRP Backup 2
The first method didn't work for me. But this method did
Restore fresh like you're going back to OOS.
Choose one method. Fastboot or MSM method.
I prefer the fastboot method.
Download fastboot ROM using the link in the Download Link section.
Extract/ un-zip
Boot your device into fastboot mode (Either do it with the advanced reboot in developer options or power off device -> boot recovery Vol - + power -> boot to bootloader or power off device -> press Vol Up + Vol down + power)

Boot to bootloader
Boot TWRP
Install TWRP
Reboot recovery
Transfer whole TWRP Folder into internal storage
Restore everything (System.img, vendor.img, boot.img and data)
Swipe to restore. If data couldn't restore then boot system, setup system, boot TWRP and restore data.
Reboot system. The first reboot might go dodgy and it did for me.
Reboot system and transfer all your internal storage stuff
done
If this did not work still. Then do the 3rd method...
Restoring a Custom ROM TWRP backup 3
If the previous 2 methods has failed for you. Then try this.
Restore fresh like you're going back to OOS.
Choose one method. Fastboot or MSM method.
I prefer the fastboot method.
Download fastboot ROM using the link in the Download Link section.
Extract/ un-zip
Boot your device into fastboot mode (Either do it with the advanced reboot in developer options or power off device -> boot recovery Vol - + power -> boot to bootloader or power off device -> press Vol Up + Vol down + power)

Reboot system. Done
If it still fails, repeat steps 1 to 15. But restore everything and you should be back on your custom ROM like you never left.
Updating OOS and Custom ROM
Update OOS with Root (Magisk)
Always do a TWRP backup before updating your OS in case
Download the full zip file of the latest OOS, transfer the zip file to internal storage NOT IN ANY FOLDER
Download and transfer twrp.zip file to internal storage

Go into Magisk Home
Press install
Press install via inactive slot
Reboot system and done
You will reboot into the next slot
You don’t have to repeat the installation to install the latest OOS in the other slot. But you should and I use this method many times and has never let me down.

First

Hey Guys,
Need a some expert advice please.
Long story short. I need to replace my OP 6T McLaren's battery as I have serious degradation in battery capacity (73% Serious Loss), meaning the battery is no longer charging to 3700mAh, max charging atm is around 2600mAh, which it drains very quickly. FYI Anything above 80% is the limit for average performance, >90% is best. You can use the OP Diagnostic App 1.0.0.9 to determine your own status. Does not work on all OP devices above 6 btw. Maybe other versions work. Anyway, will be getting OP to change the battery (no real local guys I can trust tbh, all Sammy & Apple guys...) and they want me to Factory Reset the device (complete wipe including internal storage (backed up already to PC)) before sending the device to the OP Repair Center for the obvious reasons of Privacy & Security.
On my device, I have a suite of apps that are no longer available to install with APK specially Signed, but won't be able to re-install (long story & can discuss in a PM more if there is an interest to help on this). These APK will not work any other way, I've tried! This being said, I know that TWRP Nandroids work well & have been doing these backups for yrs and have restored backups with these apps installed and it works! But I have not had to restore any as of late and TWRP Backup has somewhat changed in regards to the partition selections available. See TWRP Options pic below.
When OP returns the device to me, it will mostly likely be on the latest release of 10.3.11 (Hopefully).
Here is the current setup and runs perfectly!
OOS 10.3.11
TWRP: twrp-3.5.2_9-0-fajita
Magisk 23
The last Nandroid done today (No PW for good measure, but secured locally offline), I selected all partitions. Is this the best way to insure I get my full device backup restored?

I'm guessing that I will have to, Unlock the Bootloader, reinstall TWRP same version the Nandroid was created with in order to restore that backup.
Looking forward to hearing from you guys to make the best decision before proceed with the factory reset.
Thanking you all in advance for your time & assistance!
Cheers!

Idk if u have read Mauronofrio's XDA thread on TWRP backups. BUT NEVER BACKUP OR RESTORE SYSTEM OR VENDOR! From my guide, you don't need to backup vendor.img or system.img or anything else that's not Boot or Data FOR OOS. Make sure you have everything like a copy of everything folder/file in your internal storage before u wipe it.
BUT because you're going to wipe your device. U should have a copy of everything in case but don't backup system or vendor as they're useless and will crash your system if u restore those!
After you've got your device from repair, follow my method to restore OOS TWRP backup on your device and YOU'LL only NEED TO RESTORE BOOT + DATA. Once you have booted back to your system, everything should be there like you never left, but transfer your internal storage stuff as some apps store files in your internal storage. Once that is done, that should be it and it would be like you've never left
If the TWRP backup restore doesn't work let me know, but from my experience with going back to OOS via my TWRP backup I only backed up and restored boot + data for OOS. Custom ROMs are different but isn't the case for you

Wow, thanks for the quick reply!
I have not read Mauronofrio thread and will do!
I completely missed the system & vendor piece in your instructions....my bad!
So just to confirm, my backup that I have done with all checked off is good, but only restore Boot & Data with an exact duplicate of the current Internal Storage...right?
Going forward, when creating the Backup, just select Boot & Data and I'm good to go? Or select all Except: System Image(only) & Vendor options (both)?
Also, just so I can understand a bit better, "System" is the actual OOS? Meaning, if I restore Boot & Data on any OOS, all my apps and data will be as I never left, or we should always restore on the OOS that was current at the moment of the Backup (which I have always done in the past).
PS. I may just do the backup again, just to make sure SYSTEM & VENDOR are not there for good measure!

First off, I already posted everything you need in my last comment and that's what I usually do. Everything should be there and not like you need to pay or reply to get the extra stuff that you may need. No point in replying asking for more as I'll just be repeating myself over and over.
Just choose boot & data for TWRP backups for OOS specifically going forward and after you got your device from repair. System, vendor doesn't work in my experience and will crash your system. Only backup the .img variant which was stated by the dev (Mauronofrio) for TWRP for OP6/6T devices. Only backup system.img and vendor.img if u need to backup system+vendor, but YOU don't have to for OOS and I said this previously.
JUST DO A BACKUP OF EVERYTHING OTHER THAN SYSTEM AND VENDOR. YOU SHOULD ONLY BACKUP SYSTEM.IMG AND VENDOR.IMG NEVER SYSTEM OR VENDOR.
They never work and will increase the size of your backup and will take even longer to transfer to your storage device from your phone.
YES, to your new question. You should update/ be on the same OOS version as your TWRP backup before u restore data + boot. Restore OOS via fastboot or msm and update to get to the same version of OOS as your TWRP backup. YOU should only do this if your phone is in the wrong version of OOS as your backup after you've got it back from REPAIR.
ALWAYS BE ON THE SAME VERSION OF OOS AS YOUR TWRP BACKUP BEFORE YOU RESTORE YOUR TWRP BACKUP OF OOS!
Maybe take a copy of your wifi passwords, take a google backup in settings, take a copy of sms/call logs and contacts. Other stuff that you may not have stored just in case the TWRP backup fails, but it shouldn't. Good luck
This should be it and there isn't anything else that you'll need

Thank you!!

Hey guys, for some reason I ended up on "Unmodified System Partitions", must have tapped the screen a few times in error while handling the phone I guess.
What should I do?
Unable to go back to TWRP main menu without selecting an option.
I am rooted, on stock OOS and not doing customs ROM at this time...
What should I do?
Select "Keep Read Only"? or Swipe to "Allow Modifications"?
thanking you guys in advance for you help & guidance!

Swipe to allow modifications. But it seems that your internal storage corrupted. Not sure what you did and how you got into this situation.
After you swiped to allow modifications... If the internal storage files are a messed up, try to switch slots and reboot recovery

Cool and at least that was a easy fix

Sorry, I'm a total noob, hopefully this is an easy question to answer. Is there any way that I can tell what version of OOS my TWRP Backup contains? I can't remember what version my phone was running when I did the TWRP backup and don't want to mess it up after I restore the phone from MSM. Thanks in advance for your help!

Well u posted this twice which isn't necessary and people will try and reply. But I'm not sure if there is a way to know and as long as u copied the whole TWRP folder for that backup, u should be fine restoring it with a newer version of TWRP. If it really matters to you, then maybe try and find the latest TWRP on the date you did the backup? I think just using a newer TWRP version should be fine

Should I use the same Gapps package I flashed during clean installing when updating custom rom?

U don't have to use the same gapps package. Using a updated one would be better. But, u only have to for ROMs that don't include gapps (vanilla builds) AND the Restore script doesn't show up during installation. Opengapps doesn't have that script but nikgapps does. Using dirty flash/updating a ROM should show the restore script and if it doesn't then just reboot to recovery and flash the updated or same gapps package. This can also be the same for updating the base/vendor (use method 3 in that section of the guide). I hope this helps

Thanks for your replay)))it's my first using vanilla rom(without Gapps), so I flashed nikigapps Omni package, and my question is: should I always use the same package, or I can go with core package for example?

U can... But it doesn't really matter as a updated package works fine and u only need to use it if the nikgapps restore script doesn't show up when updating the ROM or vendor/base (OOS underneath)

I want to CHANGE custom ROMs (havoc to Lineage OS a11 to a12) I have taken TWRP back up of boot+data+system.img+ vendor.img. once I flash the new a12 Lineage plus Nikapps core plus magisk. What steps to restore data? any response is appreciated in advance. Thank you.

How to? MAGISK for Oreo Exynos

I failed similar times to root my phone with twrp 3.2.xx and 3.1.xx. I used Odin 3 v3.13.1.
Any ideas or thread links for the young padawan?
I appreciate your advice masters :good:
Using Odin Flash TWRP latest from the note 8 TWRP thread here on XDA, one on their site is not latest.
Install magisk manager app from play store.
Download magisk from the app.
Reboot to TWRP and flash the magisk file just downloaded.
Reboot and check magisk manager for root and hide.
Should be good.
Nope. Not working and still ends in a bootloop and it's unable to mount the internal storage.
Something went wrong, so.. my phone is unable to boot the system after that!
The issue is the version of TWRP and Oreo, its not yet compatible on this device, it needs porting over
If you want MAGISK you need to do it all in one hit.
Flash TWRP
Select Read Only Option.
Format Data
Reboot Recovery
Flash the DM Verify Encrypt file
Reboot Recovery, You could be able to flash files wihtout a Data mount error.
Now flash the files you want, i..e MAGISK
Once you have booted the ROM and return back to TWRP you are unable to mount Data.
This can cause various issue when flashing files
Funny you.. How can I format if the internal storage isn't able to mount?
"Select Read Only Option.
Format Data" <-- seems like a contradiction to format a missing
partition.
I think we need to wait until someone will port the twrp for Oreo. cheerio!
Because it needs to be done when you first flash it.
Once you have flash Oreo, Then TWRP, You boot into TWRP and format. You then Flash the DM Verify.
Data is accessible, its empty but accessible, Flashing any files like MAGISK work without any errors.
I have it all working on mine without any issues, I do know if i need to flash any additional files it wont work properly due to Data no longer mountable.
There is a updated version of TWRP that fixes this, but its not been ported over.

[Guide]Installing Lineage

Installing Lineage​
Few quick things.
LOS 18.1 is now official so the guide will now just be covering that.
I also want to address a common question, you can use Windows for this process. I prefer Linux, and Fastboot just works in Linux without driver issues. If you have Fastboot and ADB working in Windows already feel free to use that if you want.
Frequently asked Questions:
This looks like a lot of work, is there an easier way to install? Try the LOS Wiki Method.
Using TWRP 3.5.2_9-0​1. Start off Fresh. Install OOS using the Fastboot ROM.
Start off with a fresh install of OOS. You need the latest version of OOS 10. I typically use a the fastboot ROMs for this as it will do both slots for me at once. (Alternatively you can use TWRP and install the ZIPs and do it twice to get it on both slots, or my least favorite, the MSM Tool if you want. Doesn't matter how OOS ends up on both slots, as long as it ends up on both slots.)
I use Linux, and honestly I feel like it's easier and more reliable for fastboot and ADB so that's what I'm including here in these steps. It's easy to boot from a USB.
To create a bootable Linux flash drive you can use Unetbootin, which you can download for free here (Your other option would be to burn the ISO straight to a DVD and skip the unetbootin step):
https://unetbootin.github.io/
For Linux, I'm using Linux Mint Cinnamon, You can download for free here:
https://www.linuxmint.com/download.php
Then run unetbootin (yours will look a little different, I'm running it in Linux):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Point it to the Linux ISO, and tell it where an empty flash drive is. It will erase everything on the flash drive. Afterwards you can load whatever you want on the flash drive. However be aware when booting Linux from this drive you can't access what is on the drive (at least not by normal methods).
After this has successfully completed, reboot the PC, and boot from the USB drive. Your PC will boot into Linux (turning off the PC and removing the USB drive will make it boot up like normal again).
Next we need to install fastboot and adb. You need to open up the "start menu" and open the "synaptic package manager". You can find this stuff in the menus, however the easiest way to get to these items is to just start typing the name of the item. See below:
Search fastboot, click the boxes, choose install. Then search for ADB, click the boxes, choose install and then click apply. It's that easy it will download everything that's needed and install.
Time to open up a terminal:
Just to make sure we don't run into any problems we need to update adb and fastboot. In the terminal run these commands to update fastboot and adb (this is downloading them directly from Google).
wget https://dl.google.com/android/repository/platform-tools-latest-linux.zip
unzip \platform-tools-latest-linux.zip
sudo cp platform-tools/adb /usr/bin/adb
sudo cp platform-tools/fastboot /usr/bin/fastboot
You will also need the appropriate fastboot ROM. Fastboot ROMs available in this thread. The catch being that thread is no longer updated. So we will need to make our own fastboot rom. To do this we need two things:
1. The stock rom zip (OP Site).
2. Payload dumper. I've yet to get the one from the GitHub link to work, so I've been using the one from this Article. Direct Download Link
You need to extract the payload.bin file from the stock rom zip. Extract the payload_dumper files as well, and place everything in the same folder. Payload_dumper requires python3. Open up Synaptic again, search for python3.6 and install it. Now open a terminal so we can extract the images from the payload.bin.
Navigate to the location of payload_dumper and your payload.bin file. In my case my commands are:
cd Desktop <-- switches to the Desktop folder
cd payload_dumper <-- switches to the payload_dumper folder on the Desktop
python3 payload_dumper.py payload.bin <-- runs the payload_dumper "program" and extract the images from the payload.bin
Now would be a good time to back everything up. The phone will get wiped. Extract the fastboot images to a folder that is easy to find. I would recommend the Desktop.
Now it's time to flash all those images we just extracted using payload dumper. Place the phone in fastboot mode. You can do this using the advanced reboot menu, ADB, or the key combinations (all key combos listed below for reference):
Volume Up + Power while turning on will boot to fastboot.
Volume Down + Power while turn on will boot to recovery.
Holding Volume Up + Power should force the phone to turn off.
Volume Up + Volume Down should put your phone in Download mode for the MSM Tool.
You can flash the images one by one or use a script. My script is available here. Flashing the fastboot ROM should look something like this:
That image explained:
cd Desktop <-- Switched the directory to the Desktop the default directory when you open up the terminal is the /home directory.
cd flash <-- I put my fastboot images in a folder called flash. This stuff is case sensitive. My folder was all lowercase.
sudo fastboot devices <-- Is just checking to see if my PC can see my phone, and making sure it's in fastboot. Sudo is necessary for this distro, as both fastboot and ADB must be run as root.
sudo sh FlashThese.sh <-- Tells the terminal to run my script, since the script contains fastboot commands it must be run as root.
At the end you should get something like this:
Then just choose start form Fastboot (If you were previously on a custom ROM go straight to recovery and wipe everything). Not booting and getting dumped off at the OnePlus recovery screen is nothing to worry about. Choose your language of choice, Wipe data and cache, Erase everything (Music, pics, etc), This can not be undone, continue. After that the phone will boot. Once booted enable developer options, advanced reboot, and reboot to fastboot.
2. Installing TWRP.
First step is to boot the correct TWRP image. Grab the current TWRP from the official site. You need both files, the img file, and the installer. Once again from the terminal:
The image explained:
cd Desktop <-- Switched the directory to the Desktop the default directory when you open up the terminal is the /home directory.
sudo fastboot devices <-- Is just checking to see if my PC can see my phone, and making sure it's in fastboot. Sudo is necessary for this distro, as both fastboot and ADB must be run as root.
sudo fastboot boot twrp-3.5.2_9-0-fajita.img * <-- Sends that TWRP image to the phone to be booted temporarily. Only boot this, never run the command "flash".
Once in TWRP the phone should show up as a media device so you can copy files to it. Copy the TWRP installer over to it. Choose Install from the TWRP menu and navigate to where you placed the TWRP installer. Press on it, and swipe to confirm flash. When it is done hit the back button until you are back out to the main menu.
From the main menu choose reboot, and choose Recovery:
The first time you try and reboot the official version of TWRP it will ask you if you want to install the TWRP app. Do NOT install the app. In the settings you can disable this prompt. Your other option is just uncheck both boxes at the screen you see below when you get to it, and then click the button that says do not install. Do use the slider. At that point the phone will reboot as to recovery as you selected.
Now that you are back in TWRP that is now installed, time to wipe the phone. From the main menu choose Wipe. Swipe the factory reset slider at the bottom. Then hit back. Next hit Format Data. Type Yes to Continue. Hit back to continue. Keep hitting back till you get to the main menu.
Do NOT wipe cache, do not Wipe system, do NOT Wipe Dalvik / ART, do not add anything else, Just Factory Reset and Format Data. After doing those two Reboot to Recovery one more time. So go back into the reboot menu, choose reboot to recovery again (swipe to allow modifications if it asks). You must do this after formatting data.
3. Install Lineage
Links:
Lineage 18.1 XDA Thread
Official 6T Lineage Downloads
The phone should still be in TWRP at this point. You now need to copy Lineage to the phone. From TWRP's main menu choose install. Then navigate to your ROM .zip location and click on it. Then swipe to confirm flash.
Lineage will replace TWRP, so you need to reflash TWRP as well. Run the TWRP installer again. If it's not on the phone, just copy it over again real quick. On A/B devices ROMs get flashed to the opposite slot. Things like Gapps, Magisk, etc get flashed to the current slot. We need Lineage on both slots, so it must be flash again. Flashing it twice only needs to be done the first time as we need to get rid of OOS. For updates it just gets flashed once. After the TWRP installer has run, back out to the main menu, and choose reboot, then recovery:
Once back in TWRP flash Lineage again. From TWRP's main menu choose install. Then navigate to your ROM .zip location and click on it. Then swipe to confirm flash.
Now run the TWRP installer again. Back out to the main menu, and reboot to recovery.
4.Optional, Gapps
Links:
NikGapps <-- For Lineage 18.1 (Use the R Folders for Android 11. I recommend the "Core" version. I also tested Basic though if you want that level of Gapps. I strongly recommend you grab setup wizard out of the R Addons Folder, I used the regular setup wizard, not the pixel one.)
MindTheGapps <-- It's worth mentioning here Lineage recommends MindTheGapps for 18.1. Take your pick. I personally use NikGapps as I can use a "leaner" Gapps package.
Now that your phone is back in TWRP for the last time before booting up Lineage, it's time to install Gapps if you want them. This step is optional. Same as the other steps here, go to install, choose your OpenGapps package, Then navigate to your .zip location and click on it. Then swipe to confirm flash.
5. Very Optional, Magisk
These steps are very optional. However this is how I, root, pass safety net, and get a various apps to appear in the Play store.
Flash Magisk in TWRP. For Magisk 23, you now have to rename the Magisk.apk to Magisk.zip. Then flash it in TWRP. If you wanted to uninstall it, you rename it to uninstall.zip. If you already had an older version of Magisk installed, make sure you do not have it hidden / nenamed when installing Magisk 23 for the first time. Restore the original package before installing 23.
Magisk <-- Flash this right after Gapps.
These items are add-ons are flashed in Magisk after the first boot (Don't flash these in TWRP anymore):
MagiskHide Props Config
Busybox
To flash modules in Magisk press the puzzle piece icon. Then choose install from storage. Now just choose your addons. After flashing the icons it will have a reboot icon at the bottom. You can reboot or you can press back and flash another. After you are done reboot.
You will also need a Terminal Emulator. I personally use:
Terminal Emulator for Android
Once all these are installed the first step is setup Magisk. Under Magisk go to settings:
In version 20.4+ Magisk Hide is no longer on by default. So make sure the Magisk Hide, Hide Magisk from various forms of detection switch is flipped. Then press Hide Magisk Manager. This will bring up a box for you to choose a random name for the Magisk Manager, type whatever you want here. You can leave it Manager if you wish, but I typically change this.
Now open Magisk again. It will ask you to download it again, click ok, then manually open the app again as it says. Now we need to open Magisk hide. This is now under the shield icon, then click the arrow at the top:
These are the apps you don't want to know that you have root. Less is better. You can cause instability problems by just choosing everything. My general rule of thumb is, Google, steaming video, music, and payment apps get selected. In my experience if I come across an app that needs it and I didn't select it, I just clear cache and/or data and re-open the app and it works. There are some big multiplayer apps that ban hardware / people, so do your research (don't ask me, I don't play those games).
Next time to change the device fingerprint using MagiskHide Props Config Module. We do this using the terminal emulator. In the terminal emulator, type "su" to gain root privileges. Then type props to run the module:
Now it's just following the menus. Choose option 1 - Edit device finger print. (type 1, hit enter)
After this you will see a menu of devices. It doesn't matter what device you pick really. If you want apps / Google to think you have a OPPO or Samsung pick one of those Fingerprints. However there's a bit more to passing Safety-net than that. Since Google has changed how things work not all those fingerprints that used to work will work now. Also now you may get an error when you turn on the phone because of the security dates. The OP6T Android 10 fingerprint has no issues at this point, so use that if you want:
After choosing the fingerprint you want, it will ask you if you want to reboot. Choose yes. After rebooting, you may need to clear the cache from the play store for some apps to appear in it. You should now pass safety net. Check this in Magisk:
6. Very Optional, Ad Blocking with a Host File.
You can block many things with a hosts file, most popular would be ads. I've been use StevenBlack's host file which is a compilation of several hosts files. This is located on Github:
https://github.com/StevenBlack/hosts (Scroll down you'll see the options of what you can block)
Direct link to the hosts file I use. This will block Adware / Malware.
Unfortunately for quite some time now on this device you can no longer just use a root browser to swap the hosts file. The easiest way is to use TWRP.
First we have to make the hosts file. The hosts file must use unix / linux line endings. If you are using linux, don't worry about this, just create the file. If you are using Windows, the easiest thing to do is use Notepad++ (Free).
Notepad++ Downloads
Next one other caveat. The hosts file is quite large. I've never had much luck copy and pasting it from any other browser than Firefox (Windows or Linux), but however you get it into Notepad++ is not a big deal.
Once in you have the hosts file into Notepad++ go to Edit, EOL Conversion, and Choose Unix (LF).
Now save the file as "hosts" no ending. This does mean under file type you will need to change it to All File types *.*. Move this hosts file to your phone. Then reboot to recovery. From the main TWRP menu, choose mount. Then mount system:
Hit the back button and go to the advanced menu. Choose File Manager:
You will find your hosts file under /sdcard, wherever you placed it. In my case I placed it in a folder called ROMs. Once you locate it, press and hold it for a moment, and relase. Then choose copy file:
At this point you need to tell TWRP where you want to paste the hosts file. It belongs in the /etc folder. The only hic-cup here is depending on what you were doing in TWRP this could be (on this device) /system/etc or /system/system/etc (you will see similar folders to the image below if you are in the right place). Once you are there, press "paste?" button in the lower right corner:
After this just swipe to confirm:
You can now reboot the device, and your hosts file should now be in place. Your ad block should now be active for all apps as it's global for all connections.
7. Reboot to system.
Updating Lineage​
1. Flash Lineage.
Reboot to recovery. You can use the advanced reboot menu, or Volume Down + Power while turning the phone on. Don't wipe anything. From TWRP's main menu choose install. Then navigate to your ROM .zip location and click on it. Then swipe to confirm flash.
Lineage will replace TWRP, so you need to reflash TWRP as well. Run the TWRP installer again. After the TWRP installer has run, back out to the main menu, and choose reboot, then recovery:
2. Optional, Gapps (if you installed them once you must continue to install them or do a clean install)
Links:
NikGapps
Now that your phone is back in TWRP for the last time before booting up Lineage, it's time to install Gapps if you want them. This step is optional. Same as the other steps here, go to install, choose your OpenGapps package, Then navigate to your .zip location and click on it. Then swipe to confirm flash.
3. Reboot to system.
Last updated​Since I don't want people to have to wonder if these instructions are current, I am going to periodically test and update this post with my results. Please note I'm testing with a 6T, TMobile 6Ts are different. You can generally assume previous versions of LOS and OOS were also tested, but if you are unsure feel free to ask in this thread.
Last tested with:
OOS 10.3.7 and LOS 17.1 12-31 with TWRP 3.4.0-2
OOS 10.3.11 and LOS 18.1 05-27 with TWRP 3.5.2_9-0
This method has also been tested with:
OOS 10.3.3 and Omnirom 5-24 MicroG and Omnirom 5-24.
Cliff Notes
*TWRP 3.5.0_9-0+ Must be used with LOS 18 / 18.1
- Backup everything to the PC, so you will need to copy all your data over.
- Sync all your accounts, etc.
- In TWRP format data. Reboot recovery (This step wipes the device, make sure you backed everything up!)
- Factory Reset. (This is the slider at the bottom, do not Wipe system, do NOT Wipe Dalvik / ART, do not add anything else)
- Flash Lineage
- Flash TWRP Installer
- Reboot to Recovery
- Flash Lineage (This is only the first time, to get the AOSP rom on both slots, only do this for the first install)
- Flash TWRP Installer (This is only the first time, to get the AOSP rom on both slots, only do this for the first install)
- Reboot to Recovery (This is only the first time, to get the AOSP rom on both slots, only do this for the first install)
- Flash Gapps (Optional)
- Flash Magisk (Optional) (Remember for ver 22 the Magisk.apk gets renamed to Magisk.zip, can also be renamed to uninstall.zip for uninstalling)
- Reboot to System.
- Then you should be able to setup the device, copy everything back over. Restore your data.
After this you should be able to update Lineage as normal.
- Reboot to recovery
- Flash Lineage.
- Flash TWRP Installer
- Reboot to Recovery
- Flash Gapps. (Optional, but if you flashed them once you have to keep flashing them.)
- Flash Magisk. (Optional)
- Reboot to system.
- No loss of data, or anything.
Thanks for the guide, able to flash los 17.1 successfully.
How to go back to OOS?
Does anyone have a guide on how to go back to OOS after flashing Lineage according to Lineage's instructions?

Back up your data, use Step 1 of these instructions. That will put OOS back on your phone.
MSM Tool, always my least favorite option, but always an option.

Massive thanks for your instructions!
- at first, I tried upgrading from LOS 16.0 to LOS 17.1. I followed the instructions on the wiki, but it landed me in the qualcomm crashdump mode.
- after that I ran into your instructions, and tried to follow your update guide, but it didn't help (not very surprising I guess, but I haven't had much to lose at this point ).
- after that, I just followed your fresh install guide (i.e. flashing the fastboot room and starting from scratch), followed every step and it worked!
I wonder if it's worth updating lineage OS wiki and pointing to your instructions? There is bunch of people in this thread, who also bricked the phone into crashdump, so perhaps it could help to prevent it for someone else.
Updating to LOS 17.1 ?

Initially I had problems with updating LOS, so I returned to Stock. As more people attempted to install LOS, and this fine Original Poster "Ohio" offered such excellent, and detailed instructions, I have been running LOS 16 since February.
However, I have not updated it, since I have had Zero Issues.
But to clarify, you used this method to update to LOS 17.1 ?
- coming from LOS 16 - without first returning to a fast-boot ROM ?
Did you up-date GApps accordingly during this Flash ?
Thank You, in advance, for any assistance!

Hi, I updated my previous reply to make it a bit more clear!
Yep, I was on LOS 16. Haven't had any issues, but figured why not update if I'll have to do it eventually
So I downloaded 17.1 and used the wiki instructions, which messed the phone up
Ended up flashing fastboot rom and starting from scratch, flashed gapps and magisk according to OhioYJ's instruction and it worked.

I was using carbon ROM previously, had to move to OOS latest for flashing the lineage 17.1, believe it needs to be done if you are coming from pie, people know better correct me if I am wrong here.
As Karlicoss mentioned, it's better to follow the method posted by Ohio.

Usually this means you didnt format data, or you are using an old version of TWRP. Did you do a clean install?

Thanks a lot for your guide. Very helpfull.
I'm using it with /e/ rom.

I followed exactly as it was written. Same issues arose for me. After the phone is off then turned on no LTE. It makes phone calls and also text stuff. HOWEVER when you take out and reinsert sim LTE is enable. What is the problom?????????

Just cycling airplane mode doesnt work? This isn't a TMobile 6T is it? You are in Sim slot 1? You maybe better asking in the LOS thread, and provide log it not working and then it working when you reinsert it. Im not quite sure whats going on there.

So this means you do have to always format data for every single update??

@OhioYJ So for an update you boot to recovery flash LOS latest version then flash twrp again and then reboot to recovery second time then format data to possibly decript encrypted system and, transfer files both gapps and magisk to device and then install gapps and magisk, lastly just reboot to system?

yes it is a tmobile but it was flashed to global. TWRP is the version you are using. downloaded the lastest ROM. Weird it finds LTE at first then like I said when then phone shuts off LTE doesnt work til I take sim out.

No that would be ridiculous. Not necessary at all. You have something else going on, but I dont know what. My update procedure is exactly as listed on the OP, on two 6Ts, two different carriers.

A TMobile "converted" to global does not equal a global 6T. Logs posted in the LOS thread, may help out other TMobile users? The TMobile 6Ts introduce all sorts of quirks, and Im afraid I dont have any experience with them, so hopefully another TMobile user will be able to help.

Internal storage encrypted despite all 3 methods. Please help!

Hi!
My only encounter with rooting was several years back when it used to be a simple affair (one click rooting app based on exploits like framaroot etc), so please bear with me.
I'm on Stock Oreo 8.1 (Patch 1 Aug 2019) Sanders 1804 (India) version. I've followed various guides and have been successful in flashing TWRP 3.4.0 (Official Sanders version) and Magisk 20.4. But everytime the phone is rebooted, TWRP can't mount internal storage and shows 0mb.
I tried all three methods I could find:
1. dm-verity zip flashing - Log said fstab not found. Searched and found that from Oreo, Android's encryption approach has been changed. I couldn't make much sense out of those, though.
2. Manually replacing the `forceencrypt` to `encryptable` then flash stock recovery and format data. Didn't work.
3. Formatting data right after TWRP is flashed. Didn't work either.
The maximum it works is for one time when I can connect the device to laptop to add some zips to it to flash. It doesn't make sense to wipe the data when it's the data only that we want to back!
My purpose is to make flashable zip (nandroid) to revert to if anything goes wrong. It was phone's wifi frequent disconnection (or connected but no internet) issue which forced me to try root. I'm not much interested in new ROMs and am fine with stock itself but need a backup of all apps with data etc. Also, I couldn't understand clearly the FAQ on TWRP website that says TWRP doesn't backup internal storage but backup data. As I don't use SdCard, the internal storage is mounted in /sdcard folder only
I'll really appreciate if someone can help me.
Thanks
Found solution from a helpful guy in a Telegram group.
1. Use ONLY attached zip/img files and follow exact same order.
2. Flash TWRP, reboot to recovery
3. In Wipe section, choose Format data, type YES and confirm. Reboot to recovery again.
4. Flash DM-Verity-ForceEncrypt.zip file. Flash Magisk.zip file. Reboot to recovery.
5. (Optional) Make a backup if you want or Reboot to system. Done!

[ROM][SM-T500] Samsung Galaxy Tab A7 10.4 (2020) - LineageOS 18.1

Update: March 24 2022: This ROM has been retired and a new one based on LOS 19.1 (and TWRP based on Android 11) have taken its place. New thread here: https://forum.xda-developers.com/t/...4-2020-lineageos-19-1-and-twrp-3-6-1.4421365/
---
Update 9:46am EST July 15 2021: new builds of TWRP and LineageOS with TWRP touch fixed and LOS w/ space for Gapps is now live.
WARNING: USE AT YOUR OWN RISK.
I have successfully ported TWRP and Lineage OS 18.1 to the Samsung Galaxy Tab A7 10.4 (2020), aka SM-T500. This is my first time porting TWRP or LOS, so there may be issues unknown about at this time. Thus far, the only known issue is that the touchscreen in TWRP does not work. This can be worked around by using a USB mouse and/or accessing the device via ADB.
Here are the steps to follow:
Update your device to the latest stock ROM (as of this writing) either using the built-in system updater or via Odin. You want the build that ends with "3BUF3".
Unlock device bootloader using instructions from other threads. This will wipe your device.
Boot into download mode and flash "vbmeta_disabled_R.tar" via Odin in the "Userdata" slot to disable verified boot. This will wipe your device again.
Boot device back into download mode and flash TWRP via Odin in the "AP" slot. If you boot up into the stock ROM rather than booting directly back into download mode then go through the initial setup process of the stock ROM and enable developer tools and ensure OEM Unlocking is still enabled (VaultKeeper can possibly undo OEM Unlocking if you get to the ROM but don't go into Developer Tools and view OEM Unlocking is enabled, so make sure to do this).
Boot device into TWRP (recovery mode) and format (not wipe) your data partition. Then reboot back into TWRP.
Push LineageOS (super.new.ext4.img) to device. Ideally push it to an SD card formatted with ExFat or EXT2/3/4 (FAT/FAT16/FAT32/VFAT won't work due to file-size limitations).
Install LineageOS image to "Super" partition. Make sure to select "Install from Image" in order to show .img files in the install selector screen.
(Optional) Push NikGapps Omni to your device and install the zip. Make sure you include a "nikgapps.config" file in your "/tmp" folder that is configured to install to "system" rather than "product" or "default".
Reboot to system. You should now be in LOS with Gapps.
(Optional, but recommended): Install Magisk via TWRP
(Optional, but recommended): Run fix script to fix brightness slider not working and to make Magisk work. If you didn't install Magisk but only want the brightness fix, just enter "n" when prompted in the script. To run the script:
NOTE: Script has .txt file extension to allow hosting on AFH. Remove that so it's just .sh to match the instructions below.
Download and push to device when booted into TWRP
adb push sm-t500_fixes.sh /tmp
Enter an adb shell
adb shell
Change directories and set permissions
cd /tmp
chmod +x /tmp/sm-t500_fixes.sh
Run script
/tmp/sm-t500_fixes.sh
Tips:
If you are not seeing all of your storage space in the OS on the internal flash, boot to TWRP and format data.
Flash TWRP via "AP" slot and flash VBMeta_Disabler via "Userdata" slot in Odin.
Flash LineageOS as an Image, not as a Zip.
For Gapps, use the latest NikGapps for ARM64 and Android 11/R.
For Gapps, make sure you install to the System partition and not Product. To do this you need to slightly modify a nikgapps.config file. Instructions on that can be found on the NikGapps site.

Here are the rough steps to follow:
Unlock device bootloader using instructions from other threads.
Patch stock ROM (AP) using Magisk, then flash rooted ROM. Will likely need to wipe device after this.
Boot into rooted ROM and ensure "OEM Unlocking" is still enabled in "Developer Tools".
Boot back into download mode and flash "vbmeta_disabled_R.tar" to disable verified boot.
Boot device back into rooted stock ROM to ensure things are still functional (may require a device wipe at this step).
Boot device into download mode and use ODIN to flash TWRP recovery.tar file via "AP" slot.
Boot device into TWRP to verify functionality (hold Vol-Up + Power during boot).
Access TWRP via adb using "adb shell" or with USB mouse (touch functionality currently not working).
Format data partition on device.
Via ADB shell: twrp format data
Via USB mouse: Wipe -> Advanced -> Format Data
Boot device into download mode.
Via ADB shell: twrp reboot download
Via USB mouse: Reboot -> Download
Flash LineageOS tar file via ODIN using the "AP" slot.
If device boots into TWRP after flashing LineageOS, use USB mouse to select: Reboot -> System
Device should boot and stall for ~1m at the Samsung logo screen with red text below, then should go blank and then display LineageOS boot image.

Which slot to flash the vbmeta?

Thanks,
After flashing the vbmeta it booted into recovery automatically after what looked like a bootloop in progress, so I wiped with factory reset and then it rebooted fine. (still not sure exactly what the vbmeta does I was hoping it would make it so i didnt get that stupid pop up asking me to hit power button to continue booting due to it having the patched os) anyhow booted fine and twrp installed as you stated without touch screen but mouse with otg works fine. (great job so far) On to LOS... I think I should have checked oem lock before flashing LOS as when I installed I get stuck at boot screen that says oem lock is on... must have been from my factory reset... (facepalm)
Nope... Still sticking on boot with the following showing on the screen...
RPMB fuse not set
RPMB Provisioned
Current BInary: Custom (0x30f)
FRP Lock : OFF
OEM Lock : ON (U) {this was off verified before flash}
KG Status : Checking
Waranty Void : 0x1 (0xE02)
Quallcomm Secureboot : Enable
RP SWREV : B3 (1,1,1,3,1,1) k3 s3
secure download : enable
grdm status : normal (d0000501)
did : 041ce2d22dba
this is displayed in the corner on the bootscreen and looks like it belongs on the download screen, anyhow booting into twrp from this point works however factory reset fails with unable to mount key(something and key(something else) i figure i will let it sit a while as I know sometimes it just takes first boot a while to go through however it doesnt seem to be the problem. Have you had a positive install of the LOS? I am wondering if I had maybe gotten a bad copy of the file. When i go to install I get a pass in odin so not quite sure where to go from here other than back to the factory image any help to get this going would be great... I took on this task cause i needed someting to take my mind off the severely crappy week I have had... so looking forward to anything you can share here...
Actually, userdata is the slot I always use. It might work in both though.
Something to mention: there is not enough space on the /system partition to flash Gapps. I created a build that supports it (with a resized /system partition) but I couldn't get it to flash via Odin. The only way I got it to work was by flashing it via TWRP as an img file. I will be posting that soon. Unfortunately that will be the end of development for now as I hard-bricked the device and need to wait for a repair or replacement. Should be back developing in 2 weeks.
Nevermind what I said here.

You may need to get an otg cable for a USB mouse and choose "reboot system" from the gui. Alternatively, look at the /dev/block/by-name/misc partition and try blanking that out with dd. That has worked sometimes.

Also, from an adb shell, try "twrp reboot". Supposedly that should boot to system, but I feel like in testing I got mixed results. According to the TWRP documentation though that should be the answer.

I was able to use adb to run the TWRP Format Data command and it rebooted the tablet and now LOS has booted up. I think I'm good!
Looking forward to see how this develops
Rom is fast and snappy. Brightness control does not work. I haven’t played too much because of work but that’s what I’ve found so far
Can a mod move this to the rom release section?

I've not been able to flash this yet but I know that the latest TWRP versions have a way to fix the system partition to accept gapps. /Wipe/Advanced check system then resize. Sometimes you have to do it more than once if it is a large gapps.

I will look into that, but I'm not optimistic it will work. This device does not separately present the system partition, rather it uses a super partition which contains system, vendor, product, and odm. TWRP only shows me the super partition for working with. I was able to resize the system partition by expanding the Lineage image and file system on my pc to match the original stock system partition, then rebuilt the super image with the other partitions it needs.

how downgrade sm-a605fn from android 10 to 9

Hello, I have a Samsung Galaxy A6+ with latest fw installed.
(italian version)
A605FNXXU7CUD4
The phone is totally useless after the update to android 10, it takes AGES to perform any action, even open the Camera or open a Message.
Already tried to wipe everything, hard reset, reinstall fw. Still useless.
Since I’d like to downgrade to Android 9 to have back a useful phone, I tried to install the latest Android 9 fw with Odin.
A605FNXXS5BTB1
But it fails, saying SW REV CHECK FAIL : [aboot] Fused 7 > Binary 5
What can I do?
Is there any chance to downgrade this phone?
Thank you
1. Unlock your bootloader.
2. Flash custom recovery for your device.
3. Go to custom recovery (TWRP) and flash any downloaded custom rom (for your device), GSI or save stock firmware as flashable zip with tool like ClassyKitchen.
4. Flash Magisk or RMM-bypass-v3 in TWRP to protect your bootloader from getting locked again.
Backup your personal data at first, of course.

Almost done, but I can't find any custom rom available for download. Can someone help? Since wwith twrp I cannot install a stock rom. Thanks in advance.
I managed to flash a so called Ari's rom, but I think the phone is now bricked. It is on bootloop on the first screen of Samsung (with phone name and so on) and with SET WARRANTY BIT : KERNEL at top left. I think it is time to trash it or does someone have any hint? Thanks

I proposed three different options: custom rom, GSI (generic system image) or conversion stock firmware to flashable form. If there's no good custom rom for A6+, then don't worry - you can still try another options. Try playing with Generic System Images:
1. Flash your current stock firmware as usual in Odin.
2. Unlock bootloader and flash TWRP.
3. Go to TWRP.
4. Wipe partitions cache, dalvik, data, system (don't wipe vendor partition - it's needed).
5. Flash GSI image (recommended will be at first phhusson's AOSP (Android 9 or 10)) as "system image". You always need to choose and download "arm32_binder64" variant of img file.
6. Reboot to your new system.
Second option is to convert stock Android 9 firmware into flashable form.
1. Download ClassyKitchen tool.
2. Import downloaded Android 9 stock firmware (for your phone) into it and save it as flashable zip.
3. Go to TWRP.
4. Wipe cache, dalvik, data, system and vendor.
5. Flash your previously done zip with Android 9 as any other flashable zip in TWRP.
6. Flash Magisk or RMM-state-bypass-v3 in TWRP to prevent your bootloader from getting locked again.
7. Reboot.
I went for the second option, in Classykitchen I loaded the stock android 9 rom and selected
BUILD ZIP ROM (for recovery).
Then installed with TWRP following your wipe indications.
Success.
But when I went to install RMM-state-bypass-v3 I got the error impossile to mount /system.
So I rebooted twrp and before anything I manually mounted SYSTEM in twrp in the dedicated MOUNT menu, and I did everything again from wipe to install.
Is this procedure correct?
Success, success also for RMM-state-bypass-v3.
I rebooted but I'm again stuck in the same loop described in my previous reply.
When I selecr REBOOT in twrp, do I have to flag anything? For example System?
Regarding the first option, if I go there:

Yes, it's correct. If RMM bypass or Magisk.zip was flashed without any errors in TWRP then everything is okay. Just reboot to system in TWRP after that - there is option to reboot directly to system. First boot always can take a bit longer than next boots.

You always need to get any "arm32_binder64" (always AB) image. Gapps or vanilla is just your choice. Just get Android 9 or 10 image and flash it as "system image" (but wipe at first partitions specified in my previous post - don't wipe only Vendor partition, because it contains important things). Android 12 GSI still aren't stable. Android 11 - maybe will work properly. Android 9 and 10 should work fine. There is even short article about GSI on Galaxy A6+ with some fixes for that device attached:

But something weird happens: I install the ROM with success. If then I try to install Magisk (or Rmm) it fails with error 7.
And twrp says No Os installed if I reboot.
But if I try to install Magisk after rebooting into twrp after installing the ROM it goes without errors.
But anyway I have the issues of No Os installed.

You need to reboot to recovery after flashing new system, because just after flashing TWRP doesn't recognize it - that is why you see that "no OS installed". Just reboot your phone to recovery again (you have such option in TWRP). In case of GSI (except maybe CAOS, LineageOS Q/R mod) Magisk or RMM bypass is not needed.
Btw, in case of any problems with hardware support on GSI flash also that patch in TWRP (it may be needed to mount "Vendor" partition in TWRP before flashing that fixes):
Fixes.zip
drive.google.com
Thank you again for your help.
I already rebooted to recovery and twrp keeps saying NO OS.
I'm using twrp 3.5.2_10-0.
I'm starting to suspect that this behaviour is due to the fact that this version of twrp could be too much new and unstable for my phone.
So I'd like to install an older version of twrp with Odin, as explained here:
TWRP for SM-A605FN Samsung Galaxy A6+
How to Install TWRP 3.2.3-1 on Galaxy A6+ SM-A605FN Android 8.0.0 Oreo. Once you installed TWRP recovery on your Samsung Galaxy A6+ SM-A605FN, you can customize it, Rooting or installing custom ROM
www.recovery-mode.com
But I cannot manage to go into download mode again, even from REBOOT menu of twrp it doesn't work, I keep staying in the loop explained before.
Moreover your first option of GSI need me to go into download mode to install the latest stock ROM with Odin.
I just manage to get into the attached screen.
Any idea?
Thank you again
It's not possible to ignore that message and just flash latest stock firmware via Odin? Odin refuses flashing latest stock firmware?

But don't use TWRP older than 3.4.0, because it doesn't have support for "Vendor" partition.
Yes, I managed to ignore that screen and go in download mode again.
I tried to follow your first option since the second one was not successful.
Installed latest stock and then twrp 3.5.0-1.
Wipe as you explained, I flash the Gsi
system-quack-arm32_binder64-ab-gapps.img
The flash is very fast, but no errors, is it normal?
After that I reboot to recovery in order to flash
Disable_DM-Verity_ForceEncrypt_11.02.2020
it goes but just at the end it gives the error
failed to mount /odm no such file or directory.
And if I reboot to system the phone loops as always.
I'm losing all hope...

If you flashed it as "System Image" and it was successful then yes - should be fine. DM-Verity isn't needed for GSI - only RMM bypass v3 is sometimes needed (on CAOS, Lineage Q/R mod and maybe in case of some other images). On usual A600FN RMM bypass is not needed on phhusson AOSP. Just format "Data" partition (format, not only wipe) - it will remove encryption for you.
Procedure of flashing should be like that:
1. Wipe: cache, dalvik, data, system ("Vendor" partition leave untouched, because it's important for GSI - that is why you needed to flash stock firmware at first, because it adds vendor files for your phone, but it's needed only once, just don't wipe "Vendor").
2. Flash your GSI as "System Image".
3. Reboot phone (to recovery again).
4. Mount your "data", "vendor" and "system" partition.
5. Flash your zips: RMM bypass v3 (optionally Magisk).
5. Reboot to your new system now.
In case of any hardware support problems, reboot to TWRP again, mount "Vendor" partition and flash that fixes:

Try to boot Android 10 or Android 9 images. If it will succeed, then you can try flashing Android 11 images and check what works, and what not. According to that article

It's okay, but it's possible that you'll always need "vndklite" images for working camera.

I don't know what are those images. Can you explain better?
When I proceed with RMM bypass V3 I see the errors in the attached image. It seems like there is a problem in writing to /system.
Can this be related to the hardware support problems you mentioned?
I tried with different versions of Twrp already and with Havoc Os too.
Should I try with flashing a different ROM ?
Thanks again

Just look at filename of system images. But as I see, it's apparently important on Android 11 and newer. For now, try to boot Android 10 or 9. Let's try with that image:
https://github.com/phhusson/treble_experimentations/releases/download/v222/system-quack-arm32_binder64-ab-vanilla.img.xz
1. Decompress that image.
2. Copy to SD card or to internal storage.
3. Wipe cache, dalvik, data, system.
4. Format data partition (it's needed only once).
5. Flash downloaded and extracted file as "System Image".
6. Reboot phone to recovery (again).
7. Select in TWRP: Mount -> system, data, vendor.
8. Flash RMM bypass v3 (or Magisk).
9. Reboot now to system.
10. In case of some things not working, go back to TWRP and mount vendor partition (Mount -> tick "Vendor" -> go back to flashing zips) and flash that:

drive.google.com
11. Reboot to system again and check if now everything works properly.

Yes, because you need to mount that partitions in TWRP:
Mount -> tick "system", "vendor" and "data" - and now flash whatever you want.
The only "receipt" which isn't giving installation errors is following your last instructions but avoiding to reboot to recovery after ROM flash (used Vanilla), and using Magisk v22 with unticked the line called "skip digest check" . See attached images.
Anyway, still no success to get into android.
Also tried fixes.zip.
Maybe I have to try with sideload ?

Everything seems to be okay in your photos. What happens when you press "Reboot System"?

The phone goes into loop with the attached screen and black screen alternatively.
On the top you can see SET WARRANTY BIT: KERNEL, it should be normal right?
Do I have to set something inside MOUNT of twrp before rebooting to system?

I've never had such problem, but according to that thread it seems that it's a fault of modified kernel (so don't flash Magisk with GSI, because it patches kernel).
Try to flash stock firmware, unlock bootloader, flash TWRP, format "data" partition, wipe partitions (cache, dalvik, system, data) and flash GSI image as "system image". And reboot to system.
Don't flash RMM and Magisk for now - and check if system will run properly.
